Will do Mad Hatter!
I am still pondering about meeting dates but, it has to be between mid September and mid/end October... this has to do with 2 things, try to avoid excessive heat and the beginning of the rain (yes... it does rain in Portugal

).
What would you like to have?
I am still discussing locally... we will probably have a free day for more touristic things.
Maybe a regularity slalom course at night?
Not sure about the number of days yet... it will have to be long enough to be worth it but short enough not to be too intrusive on peoples lives.
I want to try and bring as much different nationalities as possible.
